The Bagger Ultra 25L is an ultralight frameless pack perfect for bagging peaks in the Adirondacks or for carrying around town. Featuring a small and streamlined design, the Bagger can be packed down small as a secondary pack for summit side trips or used as an ultralight minimalist pack for short adventures into the backcountry. The Bagger Ultra utilizes an included, easily removable foam sit pad as a frame and padding against your back.

The perfect ultralight frameless pack for peak bagging, overnighters, and short trips, the Sub-Nero Ultra is a smaller and slightly more stripped down version of our popular Nero Ultra Backpack.

Streamlined to only the most essential features, the Sub-Nero Ultra is great for hikers with dialed in base weights and minimalist kits.

Featuring an included sit pad, an optional webbing belt, and a variety of optional modular add-ons, the highly versatile Sub-Nero Ultra allows you to get the most out of any day, section, or thru-hike.

The Nero Ultra is a compact frameless backpack streamlined to only the most essential features making it great for hikes where less weight and volume is required.

Multiple thru-hikes of the Triple Crown trails have been completed with our Nero series backpacks, helping to prove that smaller volume frameless packs are a legitimate approach to long-distance hiking.

The Women's Arc Haul Ultra is sized for women and teenagers with a smaller build. It has shorter, slimmer shoulder straps to fit narrower shoulders. The short frame height and adjustable torso range will fit torso heights around 16-19" (40 to 48 cm). The torso height can be adjusted upwards as a young adult grows.

Aside from the women specific shoulder straps and default short torso height, this pack has all the same features as our standard Arc Haul Ultra backpacks. Our custom Curved Carbon Fiber frame system creates a gap between your back and the pack for airflow. An interchangeable padded belt hugs your hips for excellent weight transfer. Our waterproof, durable Ultra material makes this pack a true workhorse from the Sierras to the Shenandoah.

Featuring a variety of optional modular add-ons, the Women's Arc Haul Ultra will allow you to tackle those long days on the trail with a durable ultralight backpack designed to fit you.
